Replying to [comment:6 bonefish]:
> @X512: It's one thing to translate machine code from a different
architecture, it's another thing to do that in an API/ABI compatible way.
This is probably a big project and not particularly worthwhile IMO.
It's much simpler that you think. To run an application you of cource need
compiled Haiku libs for target architecture. For example if you run x86
Wonderbrush(it's closed source, isn't it?) on ARM, haiku will use x86
libraries without modification. There are no need in dynamic ABI
translation, only syscalls translation needed.
As I understand Qemu already provide everything needed to launch apps with
other target architecture on linux. Only runtime_loader
integration(runtime_loader add-ons mayble?) and diffrent syscalls
translation needed.
Sorry for offtop.
